King Juan Carlos of Spain, visibly thinner, resumed his official agenda on Monday almost two months after his last opperation. Juan Carlos, 75 underwent surgery for two herniated discs in the lumbar region on March 3, 2013. It was the fourth time in hospital in 12 months after Juan Carlos had a hip operation in November and suffered other health problems in the last two years, including a knee operation and removal of a benign tumor in the lung.

The Center for Sociological Research said Friday that on a scale from 0 to 10, those questioned for its April survey rated the royal family at 3.68, down from 4.89 in October, 2011, the last time the question was asked.

King Juan Carlos's ratings have plummeted since he went on a luxurious elephant hunting safari last year during Spain's crippling financial crisis. Recently, one of his princess daughters and her husband have been named as suspects in a corruption scandal, a first for a member of the king's immediate family.
